I stayed in this apt with mom and a neighbor, and we had a great experience. The flat is in a very convenient location, near bus routes and train (D).
It was in pristine condition and both the rental manager and owner were very helpful troubleshooting Internet and giving tips about local attractions before and during our stay.
The flat has internet and one queen size bed on a cute loft, qand two Murphy beds in the living room. The kitchen is fully equipped if you like cooking.
The flat is also walking distance from several parks, milongas, botanic garden and bike trails, and just steps away from cafes, gelato, fresh produce and good restaurants. The train takes you to downtown Buenos Aires in less than half hour, connecting with the other train lines along the way.
Highly recommended, and will definitely try to book this again when I return to Buenos Aires.
